On this day: January 18

2012: The English Wikipedia, Reddit and an estimated 7,000 other smaller websites coordinate a service blackout to raise awareness against SOPA (Stop Online Piracy Act) and PIPA (Protect IP Act). The protests were based on concerns that the bills, intended to fight copyright infringement arising outside the United States, contained measures that could harm online freedom of speech, websites and Internet communities.

Three B-52s become the first aircraft to circle the globe non-stop, Willie O'Ree breaks the NHL's color barrier, "The Jeffersons" premieres, and Jim Thorpe gets his Olympic medals back, all on this day.
